<div id="classDescription">
CGridColumn is the base class for all grid view column classes.
<br/><br/>
A CGridColumn object represents the specification for rendering the cells in
a particular grid view column.
<br/><br/>
In a column, there is one header cell, multiple data cells, and an optional footer cell.
Child classes may override <a href="CGridColumn.html#renderHeaderCellContent">renderHeaderCellContent</a>, <a href="CGridColumn.html#renderDataCellContent">renderDataCellContent</a>
and <a href="CGridColumn.html#renderFooterCellContent">renderFooterCellContent</a> to customize how these cells are rendered.</div>
